To all whom it may comem:

'Be it known that I, FERDINANDO. SonWEDT- MAN, a citizen of the UnitedStates, residing at St. Louis, Missouri, have invented a certain new anduseful Improvement inSash- Weights, of which the following isa full,clear, and exact description, such as Will enable others skilledy in theart to which `it appertains to make and use the same, reference beinghad. to the accompanyingdrawf ing is closed by amember'in which the edgeportion of the shellis embedded, said memer being preferably providedwith a cordsecuring means. I prefer to form said member from metalthat-is cast around the end portion of the incasing shell and-alsoprovide said member `with an integral projection having an opening forreceiving the cord which supports the sash weight, but, if desired, thecord-securin means can be formed by a separate piece t at is securedvtosaid member.

Figure 1 is a side elevation of a sash weight constructed in 4accordancewith my invention; Fig. 2 is a detail to `plan view of the upper end ofthe shell be ore the mem'- ber which closes same has been connectedthereto; Fig. 3 is a longitudinal sectional view of one form of moldwhich I can use in forming the member which closes the u per e'nd of theshell; and Fig. 4is a lon tu 'nal sectional view of a slightly modifieform of my lnventlon. l

Referring tothe drawings which illustrate the preferred` form of minvention, 1 designates a metal shell or ousing that incases the core ormaterial 2 of which they Wei ht is essentially composed. I ha've hereinsown the core as consistin of ground barytes but it'is immaterial, so aras my broad idea is concerned, what kind of material is used for thecore so long as it is material having pro er specific gravity. The shell1 is prefera ly of rectangular shape in cross section and is formed fromsheet metal, the lower end portion of the shell being bent or foldedinwardly to close the shell. Preferably, the l folded portions of theshell are embraced by a clip 3 through which fastening devices 4 extend.The upper end of the shell is closed by a member 5 formed from eastmetal and provided with an integral projection 6 having an eye oropening 7 for receiving the cord which supports the Weight, I prefer tocon'- nect the member 5 andpshel'l 1 together` by crimping orcorrugating the upper end portion 1a of the shell and bending itinwardly, as shownin Fig. 2, and then casting the inember 5 around saidcrimped portion.

This can be done vby lacing the crimlped shell in ,a sectional mol A, asshown in ig. 3, and sustaining it so that Aits crimpedportion'la islocated adjacent the bottom of the mold and then-pouring in the moltenmetal which forms the member 5. The mold A is 4so shaped that a member 5having an integral perforated projection 6 will be produced. 'The shell1 is then filled with the material 2 which forms the core, preferablybefore the shell'is'removed-from the mold, and thereafter the lower endportion of the shell is folded or bent inwardly .andsecured together aspreviously described. The member 5 not only forms a closure for'the endof the shell but also adds to the weight of the article.

If desired, the core of the Weight can be formed from granular materialsuch, forexample, as barytes, and metal which is poured over thegranular material while in a molten state, Fig. 4 illustrating a sashweight constructed 'm this manner; The main ad-' vantage of forming thecore of the weight from granular material and metal whichis .oured overy'same while in a molten state, 1s that I am enabled to producearticlesof different weights with a uniform4 length of,

tube or incasing shell. For exam le, a tube or shell 13 inches longiilled With arytes, as shown in Fig. 3,'will weigh about 71, ounds. Bypouring molten. metal over the arytes .so as to fill the spaces betweenthe partlcles of barytes Iincrease the Weight of the article withoutincreasing the dimensions of same. If it is desired to produce an 8%po'und weight I pour threepounds of molten iron over four pounds ofbarytes, and if it is desired to pro- .duce a '9% pound weight I poursix poundsy of mQlten metal over two pounds of barytes,

the shell and its eye, weighing 111,` pounds in each case.'

Another Aadvantage of constructing the weightin this manner is that thecore is formed integral with the member that closes the end of the`shell as the molten metal which is poured over the vgranular materialpercolates through said material and adheres `the entire edgeto themetal which forms the end closure for the shell. If desired, both endsof the shell can be embedded in cast metal which closes.

the ends of the shell and instead of forming the core of the Weight frombarytes and molten metal, as shown in Fig.` 4, the core 4 can be formedentirely from meta-1 which is poured into the shellwhile in a moltenstate.`

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is :v

1. A sash Weight composed of a core, a shell incasing said core, and acast member forming a closure for said shell and having ortion of theshell completely embedde therein; substantially as described.

. 2..A sash'weight composed of a core, a

. shell incasing said core, a cast member form- I so inga closurefor theend of said shellA and having the edge portion of the shell come'pletely embedded therein, and means on said member to which a supportingcord can be attached; substantially as described..

3. A sash weight composed of a core, .a

metal shell incasing said core, and a metal' cast member forming aclosure for said shell .and having portions of the edge of the shellcompletely embedded therein; substantially as described.

4. A sash Weight com osed of a. core, a metal shell incasing sai core, ametal cast member forming a closure for said shelland having portions ofthe edge of the lshell completely embedded therein, and means'on saidmember to Which a su 'porting cord canA be connected; substantie y asdescribed.

`5. A'sash Weight composed of a core, a

metal shell incasing said core, and a metal member cast upon the endportion of said shell to form a closure for same and rovided with anintegral device to Whic a supporting cord can be attached, said metalmember extending .beyond the endof the shell; substantially asdescribed'.

6. A sash Weight composed of a core a metal shell incasing said'core andhaving its end crimped, and a metal member arranged Aat the end of saidshell and cast upon fsaid crimped portion to form a closure for theshell; substantaill as described.

7. A sash weig t composed of a core, a metal shell incasing said coreand having its end crimped, and a metal member cast upon said crimpedportion to form a closure for the shell` and providedw'ith anintegralprojection t-o which a supporting cord can 'be attachedsubstantially as described.

8. A sash Weight comprising a' core, a shell incasingsaid core, and ametal member located beyond the end of the shell and cast -upon said endto form a closurefor same;

substantially as described.

9. A sash' weight comprising a core, a
